PHP添加密钥而不使用'&'(参考)

Question

假设我正在循环这样的数组:

foreach($cursor as $obj) { ... }

并且里面的值如下:

$obj['name'] => "foo"
$obj['surname'] => "test"

有没有办法直接从foreach中添加另一个键和值,而不使用'&'？像这样的东西:

foreach($cursor as $obj) { $obj['age'] = 24; }

但没有使用这个:

foreach($cursor as &$obj) { $obj['age'] = 24; }

提前致谢.

Answer 1

foreach($cursor as $k => $obj) { 
    $cursor[$k]['age'] = 24; //or whatever else you want to change it to
}
